<h2>Detailed Description</h2>
<p>The Q3ComboTableItem class provides a means of using comboboxes in Q3Tables.</p>
<p>A Q3ComboTableItem is a table item which looks and behaves like a combobox. The advantage of using Q3ComboTableItems rather than real comboboxes is that a Q3ComboTableItem uses far less resources than real comboboxes in <a href="q3table.html">Q3Table</a>s. When the cell has the focus it displays a real combobox which the user can interact with. When the cell does not have the focus the cell <i>looks</i> like a combobox. Only text items (i.e&#x2e; no pixmaps) may be used in Q3ComboTableItems.</p>
<p>Q3ComboTableItem items have the edit type <tt>WhenCurrent</tt> (see <a href="q3tableitem.html#EditType-enum">EditType</a>). The Q3ComboTableItem's list of items is provided by a <a href="qstringlist.html">QStringList</a> passed to the constructor.</p>
<p>The list of items may be changed using <a href="q3combotableitem.html#setStringList">setStringList</a>(). The current item can be set with <a href="q3combotableitem.html#setCurrentItem">setCurrentItem</a>() and retrieved with <a href="q3combotableitem.html#currentItem">currentItem</a>(). The text of the current item can be obtained with <a href="q3combotableitem.html#currentText">currentText</a>(), and the text of a particular item can be retrieved with <a href="q3combotableitem.html#text">text</a>().</p>
<p>If <a href="q3combotableitem.html#isEditable">isEditable</a>() is true the Q3ComboTableItem will permit the user to either choose an existing list item, or create a new list item by entering their own text; otherwise the user may only choose one of the existing list items.</p>
<p>To populate a table cell with a Q3ComboTableItem use <a href="q3table.html#setItem">Q3Table::setItem</a>().</p>
<p>Q3ComboTableItems may be deleted with <a href="q3table.html#clearCell">Q3Table::clearCell</a>().</p>
<p>Q3ComboTableItems can be distinguished from <a href="q3tableitem.html">Q3TableItem</a>s and <a href="q3checktableitem.html">Q3CheckTableItem</a>s using their Run Time Type Identification number (see <a href="q3combotableitem.html#rtti">rtti</a>()).</p>

<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="Q3ComboTableItem"></a>Q3ComboTableItem::Q3ComboTableItem ( <a href="q3table.html">Q3Table</a> * <i>table</i>, const <a href="qstringlist.html">QStringList</a> &amp; <i>list</i>, bool <i>editable</i> = false )</h3>
<p>Creates a combo table item for the table <i>table</i>. The combobox's list of items is passed in the <i>list</i> argument. If <i>editable</i> is true the user may type in new list items; if <i>editable</i> is false the user may only select from the list of items provided.</p>
<p>By default Q3ComboTableItems cannot be replaced by other table items since <a href="q3tableitem.html#isReplaceable">isReplaceable</a>() returns false by default.</p>
